i wanted to know on tunning a half bridge turbo set up how many out there are running plenums on ther jw or jaytech manifolds ,i've heard from some people thats is ok just to port match the intake to the motor and that a plenum its not needed , and some have told me is needed for when the bridges open up it will get that extra air from the plenum, any one has some info on this is apreciated.

 

get one!
